Detailed Description

1. First embodiment

First, the structure of the complex apparatus 10 will be described. As shown in fig. 1 and 2, the complex apparatus 10 includes a reading mechanism 11 and a recording mechanism 12, the reading mechanism 11 includes a reading portion 63 for reading information of the original S and an original discharge port 64 for discharging the read original S, and the recording mechanism 12 includes a recording portion 50 for recording information on the recording medium M and a medium discharge port 58 for discharging the recorded recording medium M. The complex apparatus 10 further includes a control unit 100 (fig. 5), and the control unit 100 controls the reading mechanism 11 and the recording mechanism 12. The complex apparatus 10 of the present embodiment can simultaneously perform reading of the original S by the reading mechanism 11 and recording of the original S on the recording medium M by the recording mechanism 12.

The composite device 10 is placed on a horizontal plane, and the front-rear direction of the composite device 10 is a direction along the Y axis, and the left-right direction (or the width direction) orthogonal to the Y axis is a direction along the X axis. The vertical direction (vertical direction) with respect to the horizontal plane is a direction along the Z axis.

The composite apparatus 10 includes a rectangular parallelepiped housing 20. A base frame 26 for supporting each part of the composite device 10 is provided at the lower part of the housing 20. The housing 20 accommodates a recording unit 50, a reading unit 63, and the like.

At the lower part of the composite device 10, a plurality of feet 28 are provided. The leg 28 is coupled to the base frame 26 and supports the housing 20. The foot 28 is, for example, a castor.

A rectangular opening 31 is provided in the front surface of the housing 20 in the +y direction, and has a space extending in the-Y direction. A feeding portion 30 is disposed in the space, and a roll body R is detachably provided to the feeding portion 30. The roll body R has a cylindrical shape in which the recording medium M (e.g., paper) is wound in a roll shape and is overlapped on the core member 22. The recording medium M unwound from the reel body R is fed toward the recording portion 50 side. In the feeding portion 30 of the present embodiment, the two roll bodies R are housed side by side in the height direction. Both end portions of the roll body R are supported by a holding member 24 that rotatably holds the roll body R.

The complex apparatus 10 includes a medium conveying section 40 in the housing 20. The medium conveying section 40 conveys the recording medium M unwound from the roll R along the conveying path 41. The medium conveying section 40 includes a conveying path forming section 43 and conveying rollers 44 (44 a, 44 b). The conveyance path forming section 43 is located in the-Y direction with respect to the roll body R provided. The conveyance path forming section 43 forms a roll paper supply path 42 that guides the recording medium M unwound from the roll body R toward the-Y direction side of the housing 20. The conveying roller 44 conveys the recording medium M on the conveying path 41. The conveying roller 44 is a pair of rollers rotatably supported about axes along the width direction, and is constituted by a driving roller and a driven roller. The front and rear surfaces of the recording medium M are sandwiched and supported by the respective driving rollers and driven rollers. The driving roller is driven to rotate by the forward rotation of the driving motor, so that the recording medium M is conveyed toward the support portion 54 through the conveying path 41, and is conveyed from the support portion 54 toward the medium discharge port 58. The medium discharge port 58 is provided on the front surface of the housing 20 in the +y direction.

Further, a medium position detecting portion 45 is provided, and the medium position detecting portion 45 is capable of detecting a position of the tip of the recording medium M. The medium position detecting unit 45 includes, for example, a rotary encoder. The rotary encoder is disposed on a drive motor connected to the drive roller of the conveying roller 44 a. The rotary encoder is connected to the control unit 100. The rotary encoder converts the mechanical displacement amount of rotation into an electrical signal, and processes the signal to detect the position, the speed, and the like.

The rotary encoder is configured by a slit disk fixed to a rotary shaft of a drive motor, and a position detector provided at a position where a peripheral edge of the slit disk passes. The slit disk is provided with a plurality of position detecting slits at equal intervals along the periphery thereof so as to span the entire periphery. The position detector includes a light emitting portion including a light emitting diode and a light receiving portion including a phototransistor (phototransistor) so as to face each other through a peripheral edge of the slit disk. When light from the light emitting section passes through the position detecting slit of the slit disk and is received by the light receiving section, an electric signal is outputted from the light receiving section.

The recording unit 50 records (prints) an image on the recording medium M conveyed on the conveying path 41. The recording unit 50 includes: a head 51 that ejects ink toward the recording medium M; a carriage 52 on which the head 51 is mounted; and guide rails 53 arranged along the width direction. The recording unit 50 further includes a moving mechanism (not shown) that reciprocates the carriage 52 along the guide rail 53. A support portion 54 for supporting the recording medium M is provided at a position facing the head 51. The head 51 ejects ink while reciprocating in the width direction of the recording medium M together with the carriage 52, thereby recording information such as an image on the recording medium M supported by the support portion 54.

Further, a medium detection sensor 46 is disposed between the conveying roller 44a and the head 51 on the conveying path 41. The medium detection sensor 46 is a sensor that detects the presence or absence of the recording medium M. The medium detection sensor 46 is connected to the control section 100, and a driving motor connected to the driving roller of the conveying roller 44a is controlled based on detection data from the medium detection sensor 46. After the recording medium M cut by the cutting unit 55 described later is discharged from the medium discharge port 58, the control unit 100 controls the medium conveying unit 40 to move the leading end of the recording medium M upstream of the head 51 and to move the carriage 52 to the standby position based on the detection data of the medium detection sensor 46.

The medium detection sensor 46 is, for example, a photointerrupter (photo interrupter), and includes a light emitting portion that emits light and a light receiving portion that receives the light emitted from the light emitting portion. As the light emitting element of the light emitting portion, for example, an LED (Light Emitting Diode: light emitting diode) light emitting element, a laser light emitting element, or the like can be applied. The light receiving unit is constituted by a phototransistor, an optical integrated circuit (Photo IC), or the like. The change in the amount of light received between the light emitting unit and the light receiving unit is converted into an electrical signal and output as detection data. The control unit 100 determines whether or not the recording medium M is present based on the detection data, and controls a drive motor that drives the conveying roller 44 a. The control unit 100 detects the position of the leading end of the recording medium M by the medium position detection unit 45 (rotary encoder).

A cutting section 55 is disposed downstream in the conveying direction of the recording section 50. The cutting unit 55 cuts the recording medium M after the recording is completed. The cutting section 55 has a cutting blade 56, and cuts the long recording medium M at a predetermined position by the cutting blade 56 being reciprocated in the width direction (left-right direction).

The cut single recording medium M is discharged from the discharge unit 57 in the +y direction. The discharge portion 57 is disposed downstream of the cutting portion 55 in the conveying direction. The discharge portion 57 includes a medium discharge port 58 and a discharge port member 59. The discharge port member 59 is located in the +y direction with respect to the supporting portion 54, supports the recording medium M passing through the supporting portion 54, and guides the recording medium M to the medium discharge port 58. The medium discharge port 58 is formed in an open manner above the discharge port member 59. The recording medium M cut by the cutting section 55 is discharged to the outside of the complex apparatus 10 through the medium discharge port 58.

A stacker 35 is provided between the discharge port member 59 and the feeding portion 30 in the up-down direction. The stacker 35 has a length in the left-right direction equal to the discharge port member 59, and is configured in a sheet shape. The stacker 35 is housed inside the casing 20 and is movable in the +y direction. When the stacker 35 is used, the stacker 35 is pulled out in the +y direction and is used in a state where the stacker is deflected. In this state, the cut recording medium M is discharged from the medium discharge port 58, whereby the recording medium M is loaded on the stacker 35.

An ink cartridge 39 is provided in the housing 20. The ink cartridge 39 accommodates ink. The ink cartridge 39 is detachably provided with respect to the cartridge holder 38. The user can replace the ink cartridge 39 from the front surface side of the complex apparatus 10. The ink stored in the ink cartridge 39 is supplied to the head 51 through a hose.

The reading mechanism 11 is disposed above the front surface side in the housing 20. A document feed port 61 is provided in the front portion of the +z direction end surface (upper surface) of the housing 20. The document feed port 61 is an opening formed to extend in a direction along the X axis. The original S is conveyed into the reading mechanism 11 via the original feed port 61, and a reading process of reading information of the original S by the reading section 63 is performed. The document S subjected to the reading process is discharged from the document discharge port 64 to the outside of the casing 20. The structure of the reading mechanism 11 will be described later.

An operation unit 15 capable of giving an operation instruction to the complex apparatus 10 is provided on the upper surface of the housing 20. The operation unit 15 includes a display panel such as a liquid crystal. The operation unit 15 is provided with a pitch mechanism, and can be used so as to be tilted to a position where the operation unit 15 is easy to operate.

Next, the structure of the reading mechanism 11 will be described.

As shown in fig. 3, the reading mechanism 11 includes: a document feed port 61 in which a document S is inserted; a document conveying section 62 that conveys a document S inserted from a document feed port 61 along a conveying path FR; a reading section 63 that reads information such as an image of the document S conveyed by the document conveying section 62; a pressing mechanism 85 that presses the original S toward the reading section 63; a document discharge port 64 for reading, through which the read document S is discharged; a sensor section 65 capable of detecting the original S.

The conveyance path FR extending from the document feed port 61 to the document discharge port 64 is inclined in the +y direction in the-Z direction. The first discharge direction D1, which is the discharge direction of the original S in the original discharge port 64, is a direction including the component in the +y direction. In detail, the conveyance path FR is inclined at a predetermined angle that forms an acute angle with respect to the-Z direction. Thus, the original S discharged from the original discharge port 64 is away from the original discharge port 64. In particular, when the leading end portion of the original S discharged from the original discharge port 64 is curled, the leading end portion may enter the inside of the complex apparatus 10 from the medium discharge port 58 when the leading end portion approaches the medium discharge port 58. By including the component in the +y direction in the first discharge direction D1, the possibility that the original S enters the inside of the complex apparatus 10 from the medium discharge port 58 is reduced.

The document conveying section 62 includes: an upstream drive roller pair 71; a first driving roller pair 72 disposed on the downstream side of the upstream driving roller pair 71 in the conveying path FR; and a second driving roller pair 73 disposed downstream of the first driving roller pair 72 in the conveying path FR. The upstream driving roller pair 71, the first driving roller pair 72, and the second driving roller pair 73 each convey the original S in a pinch manner. The reading section 63 is arranged between an upstream driving roller pair 71 and a first driving roller pair 72 on the conveying path FR. The document feeding section 62 includes a feeding motor 62M (see fig. 5) for reading as a driving motor that drives the upstream driving roller pair 71, the first driving roller pair 72, and the second driving roller pair 73. In the present embodiment, the meaning of upstream on the conveyance path FR means upstream in the conveyance direction from the document feed port 61 toward the document discharge port 64. Similarly, the meaning downstream on the conveyance path FR means downstream in the conveyance direction from the document feed port 61 toward the document discharge port 64.

The upstream driving roller pair 71 is located upstream of the readable position SP of the reading section 63 on the conveyance path FR, and has an upstream driving roller 74 and an upstream driven roller 75. The upstream driving roller 74 is rotatably supported about the axis of an upstream driving shaft 741 extending along the X axis. The outer peripheral surface of the upstream driving roller 74 is covered with an elastically deformable member. For example, the outer peripheral surface of the upstream driving roller 74 is covered with synthetic rubber. The upstream driving roller 74 is driven by the conveyance motor 62M. The upstream driven roller 75 is rotatably supported about an axis of an upstream driven shaft 751 extending along the X axis. The axis of the upstream driving shaft 741 and the axis of the upstream driven shaft 751 are substantially parallel.

The first driving roller pair 72 is located downstream from the readable position SP of the reading section 63 on the conveying path FR, and has a first driving roller 76 and a first driven roller 77. The first driving roller 76 is rotatably supported about an axis of a first driving shaft 761 extending along the X axis. The first driving roller 76 is driven by the conveying motor 62M. The first driven roller 77 is rotatably supported about an axis of a first driven shaft 771 extending along the X axis. The axis of the first driving shaft 761 and the axis of the first driven shaft 771 are substantially parallel.

The second driving roller pair 73 is located downstream of the readable position SP of the reading section 63 on the conveying path FR, and has a second driving roller 78 and a second driven roller 79. The second driving roller 78 is rotatably supported about an axis of a second driving shaft 781 extending along the X axis. The second driving roller 78 is driven by the conveying motor 62M. The second driven roller 79 is rotatably supported about an axis of a second driven shaft 791 extending along the X axis. The axis of the second driving shaft 781 and the axis of the second driven shaft 791 are substantially parallel.

The reading unit 63 of the present embodiment includes a first CIS module 80A and a second CIS module 80B as the contact image sensor (Contact Image Sensor, CIS) module 80. The CIS module 80 includes a light source 801 such as an LED that irradiates light onto the document S, a light receiving element 802 such as a CMOS sensor that receives reflected light from the document S being conveyed, and a contact glass 803 that contacts the document S. The original S is conveyed while being in contact with the transmission surface 804 of the contact glass 803. The light source 801 irradiates light to the original S via the contact glass 803, and the light receiving element 802 reads the reflected light from the original S.

The control of the light source 801 and the light receiving element 802 of the CIS module 80 may be performed by the control unit 100 or may be performed by a dedicated control unit such as a microprocessor provided in the CIS module 80. The read results of the light receiving elements 802 based on the CIS module 80 are synthesized by the control section 100 to generate image data.

In the CIS module 80 of the present embodiment, the light receiving elements 802 are arranged along the X axis. The CIS module 80 reads the opposite portion of the original S at a time within a range of the dimensional amount thereof along the X axis. In the present embodiment, the first CIS module 80A and the second CIS module 80B partially overlap each other in the X axis.

The reading mechanism 11 of the present embodiment includes, as the pressing mechanism 85, a pressing mechanism 85A that applies a force in a direction in which the original S is pressed against the contact glass 803 of the first CIS module 80A, and a pressing mechanism 85B that applies a force in a direction in which the original S is pressed against the contact glass 803 of the second CIS module 80B. The pressing mechanism 85 is provided at a position between the upstream driving roller pair 71 and the first driving roller pair 72 in the conveying direction of the original S where the original S can be pressed.

The pressing mechanism 85 includes a pressing plate 86 that can contact the original S, and a pressing spring 87 that biases the pressing plate 86 in a direction approaching the transmission surface 804. The pressing plate 86 of the pressing mechanism 85A faces the transmission surface 804 of the first CIS module 80A across the conveyance path FR. The pressing plate 86 of the pressing mechanism 85B faces the transmission surface 804 of the second CIS module 80B across the conveyance path FR.

The document discharge port 64 is a space sandwiched between the discharge guide 88 and a wall 681 facing the discharge guide 88 across the conveyance path FR.

The sensor section 65 includes a first sensor 651 capable of detecting the original S, and a second sensor 652 capable of detecting the original S at a position different from the first sensor 651. The first detection position DP1, which is the detection position detected by the first sensor 651, is located upstream of the transmission surface 804 of the first CIS module 80A in the conveying direction of the document S. The first sensor 651 detects the original S when the original S is located at the first detection position DP1, and the first sensor 651 does not detect the original S when the original S is not located at the first detection position DP 1. The second detection position DP2, which is a detection position detected by the second sensor 652, is located downstream of the second driving roller pair 73 in the conveying direction of the original S. The second sensor 652 detects the original S when the original S is located at the second detection position DP2, and does not detect the original S when the original S is not located at the second detection position DP 2.

The discharge guide 88 is provided on the-Z direction side of the second driving roller pair 73. The discharge guide 88 is a plate-like member extending along the X axis. The discharge guide 88 has a guide surface 881 facing in the +z direction. The guide surface 881 is inclined so as to be inclined downward in the-Z direction as going toward the +y direction. The discharged original S is discharged along the guide surface 881. That is, the first discharge direction D1, which is the direction in which the original S is discharged, is a direction that decreases in the-Z direction as going toward the +y direction.

As shown in fig. 4, the first conveying direction FD1, which is the conveying direction of the original S at the nip position N1 of the first driving roller pair 72, is a direction including more components of lead immediately below-Z than the +y direction. In the present embodiment, the first conveying direction FD1 is a direction along a tangential line passing through the first driving roller 76 at the nip position N1. In the present embodiment, an intersection point of a straight line connecting the center of the first driving shaft 761 and the center of the first driven shaft 771 and the outer peripheral surface of the first driving roller 76 can be regarded as the nip position N1.

The second conveying direction FD2, which is the conveying direction of the original S in the nip position N2 of the second driving roller pair 73, is a direction including more components of lead immediately below-Z than components of +y direction. Further, the proportion of the component in the +y direction of the second conveyance direction FD2 with respect to the component of the vertically below-Z is larger than the proportion of the component in the +y direction of the first conveyance direction FD1 with respect to the component of the vertically below-Z. In the present embodiment, the second conveying direction FD2 is a direction along a tangential line of the second driving roller 78 passing through the nip position N2. In the present embodiment, an intersection point of a straight line connecting the center of the second driving shaft 781 and the center of the second driven shaft 791 and the outer peripheral surface of the second driving roller 78 may be regarded as the nip position N2.

The first unit feed amount by which the first drive roller 76 can convey the original S by one rotation is larger than the second unit feed amount by which the second drive roller 78 can convey the original S by one rotation. That is, the peripheral speed of the second drive roller 78 is smaller than the peripheral speed of the first drive roller 76. The difference in circumferential speed between the first drive roller 76 and the second drive roller 78 is set according to the difference in roller diameter in the present embodiment. That is, in the present embodiment, the diameter of the second driving roller 78 is smaller than the diameter of the first driving roller 76, and the first driving roller 76 and the second driving roller 78 are driven at the same rotational speed by the conveying motor 62M. Accordingly, the peripheral speed of the second drive roller 78 is smaller than the peripheral speed of the first drive roller 76. In the present embodiment, the roller diameter of the first driving roller 76 and the roller diameter of the second driving roller 78 are different, but the first unit feeding amount of the first driving roller 76 may be larger than the second unit feeding amount of the second driving roller 78. For example, the first driving roller 76 and the second driving roller 78 may have the same roller diameter, and the rotation speed of the first driving roller 76 may be larger than the rotation speed of the second driving roller 78. Further, the roller diameter and the rotation speed may be different from each other.

Since the second unit feeding amount of the second driving roller 78 is smaller than the first unit feeding amount of the first driving roller 76, the second driving roller pair 73 does not pull the original S downstream. Therefore, the deviation of the conveying speed at the portion of the readable position SP of the original S due to the conveying force when the second driving roller pair 73 conveys the original S can be suppressed.

Further, the sandwiching force by the second driving roller 78 and the second driven roller 79 constituting the second driving roller pair 73 is smaller than the sandwiching force by the first driving roller 76 and the first driven roller 77 constituting the first driving roller pair 72.

The first driven roller 77 constituting the first driving roller pair 72 is biased toward the first driving roller 76 by a first spring 831. Therefore, the nipping force of the first drive roller pair 72 for nipping the original S is determined by the urging force of the first spring 831. The first spring 831 is a compression spring. The first spring 831 is not limited to a compression spring, and may be any other spring such as a cylindrical spring, for example, as long as a force can be applied to the first driven roller 77.

The second driven roller 79 constituting the second driving roller pair 73 is biased toward the second driving roller 78 by a second spring 841. Therefore, the holding force of the second driving roller pair 73 for holding the original S is determined by the urging force of the second spring 841. The second spring 841 is a cylindrical spring. The second spring 841 is not limited to a cylindrical spring, and may be any other spring such as a compression spring, as long as a force can be applied to the second driven roller 79.

The spring constant of the second spring 841 is smaller than that of the first spring 831. That is, the second spring 841 exerts a smaller force than the first spring 831. Therefore, the nip force of the second drive roller pair 73 is weaker than that of the first drive roller pair 72.

Next, a control structure of the complex apparatus 10 will be described.

As shown in fig. 5, the complex apparatus 10 includes a control unit 100. The control unit 100 includes: a CPU101, a memory 102, a control circuit 103, and an I/F (interface) 104. The CPU101 is an arithmetic processing device. The memory 102 is a device for storing a program of the CPU101, securing a work area, or the like, and has a storage element such as a RAM or an EEPROM.

The control unit 100 is connected to the operation unit 15. The control unit 100 receives an operation signal output when the operation unit 15 is operated. When a predetermined operation is performed on the operation unit 15, the operation unit 15 outputs a read request signal, and when the read request signal is input to the control unit 100, the control unit 100 receives a read request. When receiving the reading request, the control unit 100 controls the reading means 11 and the recording means 12, reads the image of the original S by the reading unit 63 of the reading means 11, generates image data, and records the image based on the generated image data on the recording medium M by the recording means 12.

The sensor unit 65 is electrically connected to the control unit 100. The control section 100 determines the state of the original S based on the change in the output of the sensor section 65.

The first sensor 651 is electrically connected to the control unit 100 as the sensor unit 65 electrically connected to the control unit 100. The output by the first sensor 651 when the first sensor 651 detects the original S is a first output, and the output by the first sensor 651 when the first sensor 651 does not detect the original S is a second output. When the output from the first sensor 651 changes from the second output to the first output, the control unit 100 determines that the top end of the document S passes the first detection position DP1. When the leading end of the document S passes the first detection position DP1, the control unit 100 starts counting the rotation amount of the conveyance motor 62M by a counter not shown. The control unit 100 combines the reading results read by the light receiving element 802 of the reading unit 63 based on the position of the original S estimated from the count value.

When the output from the first sensor 651 is changed from the first output to the second output, the control unit 100 determines that the rear end of the document S passes the first detection position DP1. When the rear end of the original S passes the first detection position DP1, the control unit 100 starts counting by the counter. The control unit 100 executes a document S holding operation described later based on the position of the rear end of the document S estimated from the count value.

The second sensor 652 is electrically connected to the control unit 100 as the sensor unit 65 electrically connected to the control unit 100. The output by the second sensor 652 when the second sensor 652 detects the original S is the third output, and the output by the second sensor 652 when the second sensor 652 does not detect the original S is the fourth output. The second sensor 652 detects the original S held by the second driving roller pair 73 in a holding operation of the original S described later. In the holding operation of the original S, when the output from the second sensor 652 is changed from the third output to the fourth output, the control unit 100 determines that the original S held by the second driving roller pair 73 is removed from the complex apparatus 10.

The control unit 100 is configured to be able to perform bidirectional communication with an external device (for example, a personal computer) via the I/F104. The control unit 100 can input a recording request signal, a reading request signal, and a reading request signal output from an external device connected to the I/F104. The I/F104 may be configured to be capable of wired connection or wireless connection.

Next, a control method related to the operation of holding the original S by the reading mechanism 11 will be described. In detail, when the original S discharged from the original discharge port 64 falls down carelessly, the original S may be deformed. Therefore, in the present embodiment, the holding operation for holding the original S discharged from the original discharge port 64 is performed in the reading mechanism 11.

Hereinafter, description will be made specifically.

As shown in fig. 6, first, in step S11, the control unit 100 causes the reading process and the recording process to be executed. Specifically, when the reading request is received, the conveyance motor 62M is controlled so that the upstream driving roller pair 71, the first driving roller pair 72, and the second driving roller pair 73 are rotated, whereby conveyance of the original S inserted into the original feeding port 61 is started. After the start of conveyance of the original S, the control section 100 controls the reading section 63 so that an image (information) of the original S is read when the original S passes through the readable position SP.

In step S12, the control section 100 determines whether or not the rear end of the original S passes the first detection position DP1 after the conveyance of the original S is started in step S11. In more detail, the output by the first sensor 651 is monitored from a first output indicating that the original S is detected to a second output indicating that the original S is not detected. When the output from the first sensor 651 changes from the first output to the second output (yes), the control unit 100 determines that the rear end of the document S passes the first detection position DP1.

The control unit 100 controls the light sources 801 of the CIS modules 80 so as to irradiate the document S with white light. The control unit 100 receives the result of detection of the plurality of light receiving elements 802 via the red, blue, and green color filters. As described above, when the top end of the original S passes the first detection position DP1, counting of the rotation amount of the conveying motor 62M is started by the counter (step S13). The control unit 100 combines the detection results detected by the light receiving elements 802 of the CIS modules 80 based on the count value counted by the counter, thereby generating image data such as characters and images recorded on the original S. The control unit 100 also stores the generated image data in the memory 102.

Further, the control section 100 performs recording on the recording medium M by the recording mechanism 12 based on the image data stored in the memory 102. Specifically, the control unit 100 controls the medium conveying unit 40 to convey the recording medium M. Then, the control unit 100 controls the recording unit 50 so that the ink is ejected onto the recording medium M when the recording medium M passes through the recording position where the recording is performed by the recording unit 50. Thereby, the image data is recorded on the recording medium M. The control unit 100 discharges the recording medium M on which the image data is recorded toward the medium discharge port 58.

In step S14, the control unit 100 determines whether or not the count value counted by the counter exceeds a predetermined value set in advance (step S14).

Here, the predetermined value used in the determination in step S14 is a value on the conveyance path FR corresponding to the length between the first detection position DP1 and the gripping position N1 detected by the first sensor 651. In more detail, the predetermined value is set based on the length between the first detection position DP1 and the nip position N1 on the conveying path FR and the circumferential speed of the first driving roller 76. Therefore, the predetermined value is set to a value at which the rear end of the original S is located at the nip position N1 when the count value reaches the predetermined value after the rear end of the original S passes through the first detection position DP 1. Therefore, the determination in step S14 performed by the control section 100 can also be regarded as a determination as to whether or not the rear end of the original S passes the nip position N1.

When it is determined that the count value counted by the counter exceeds the predetermined value (yes), the control unit 100 ends counting the count value by the counter (step S15), and controls the conveyance motor 62M to stop conveyance of the original S (step S16). Therefore, the control section 100 stops the rotation of the upstream driving roller pair 71, the first driving roller pair 72, and the second driving roller pair 73 in a state where the original S is not located at the readable position SP of the reading section 63 and the original S is not located at the nip position N1. In step S16, the control section 100 stops conveyance of the original S before the trailing end of the original S passes the nip position N2 of the second drive roller pair 73. In the present embodiment, although the control unit 100 executes step S16 after executing step S15, the control unit may execute step S16 before the trailing end of the document S passes through the nip position N2, or may execute step S16 before step S15, or may execute step S15 and step S16 in parallel.

When the conveyance of the original S is stopped in step S16, the control unit 100 holds the original S by the complex apparatus 10 without falling from the original discharge port 64, as shown in fig. 7. More specifically, the document S is held by the reading mechanism 11 (the complex apparatus 10) in a state in which the vicinity of the rear end of the document S is nipped by the second driving roller pair 73 and the tip end of the document S is downward suspended from the document discharge port 64. This can prevent the document S from being inadvertently dropped from the document discharge port 64 when the image is read by the reading section 63.

Here, a positional relationship between the document discharge port 64 of the reading mechanism 11 and the medium discharge port 58 of the recording mechanism 12 will be described.

As shown in fig. 8, the document discharge port 64 is arranged above the medium discharge port 58 in the vertical direction. Further, the second advancing path MD2, which is the advancing path along which the leading end of the recording medium M discharged from the medium discharge port 58 passes, and the original S discharged from the original discharge port 64 are in a positional relationship intersecting each other at the intersecting position CP.

The first travel path MD1 through which the leading end of the document S discharged from the document discharge port 64 passes is a first discharge direction D1 and is a-Z direction including a component in the +y direction in a state where the leading end of the document S is conveyed while being supported by the discharge guide 88. Thereafter, the leading end of the original S is discharged to the outside from the original discharge port 64, and the direction is the-Z direction.

On the other hand, the second travel path MD2 through which the leading end of the recording medium M discharged from the medium discharge port 58 passes is the second discharge direction D2 and is substantially the +y direction (horizontal direction) in a state where the leading end of the recording medium M is conveyed while being supported by the discharge port member 59, and thereafter, is the-Z direction in a state where the leading end of the recording medium M is discharged to the outside from the medium discharge port 58.

The intersecting position CP at which the original S and the recording medium M intersect is a position at which the first advancing path MD1 through which the leading end of the original S passes and the second advancing path MD2 through which the leading end of the recording medium M passes intersect, and is a position substantially along the upper surface of the discharge port member 59, and is a position in the +y direction of the discharge port member 59.

Therefore, after the leading end of the original S is located at the intersecting position CP, the original S obstructs the second advancing path MD2 of the leading end of the recording medium M in the case where the recording medium M is discharged in the second discharge direction D2. That is, when the leading end of the original S is located at the intersecting position CP and the leading end of the original S is located below the intersecting position CP, the leading end of the recording medium M is blocked by the second advancing path MD2.

In the complex apparatus 10 of the present embodiment, the first angle θ1, which is the angle of the first discharge direction D1 of the document in the document discharge port 64 in the horizontal direction, in the reading mechanism 11 is larger than the second angle θ2, which is the angle of the second discharge direction D2 of the recording medium M in the medium discharge port 58 in the horizontal direction, in the recording mechanism 12.

That is, in the complex apparatus 10 including the reading means 11 and the recording means 12, since the original S is held downward instead of being discharged in the horizontal direction, it is possible to suppress occurrence of damage or crease on the original S.

On the other hand, in a state in which the holding operation of the original S is performed, that is, in a state in which the original S hangs down from the original discharge port 64, the leading end of the original S is located below beyond the intersecting position CP, and as shown in fig. 7, the medium discharge port 58 through which the recording medium M is discharged is blocked by the held original S, so that the second advancing path MD2 of the leading end of the recording medium M is blocked. In this way, in a state where the medium discharge port 58 is blocked by the original S, when the recording medium M is discharged from the medium discharge port 58, the tip of the discharged recording medium M comes into contact with the original S. Further, since the discharge operation of the recording medium M is performed in a state where the movement of the recording medium M in the +y direction is blocked by the original S, the recording medium M is jammed in the housing 20, and a conveyance jam occurs.

Therefore, in the control unit 100 of the complex apparatus 10 according to the present embodiment, the reading means 11 and the recording means 12 are controlled to suppress such conveyance failure.

Specifically, when the top end of the recording medium M is discharged from the medium discharge port 58 in a stopped state in which the discharge of the original S is stopped at a position of the second advance path MD2 where the top end of the recording medium M discharged from the medium discharge port 58 is blocked by the original S discharged from the original discharge port 64, the control unit 100 executes a predetermined operation for releasing the stopped state before the top end of the recording medium M reaches the intersecting position CP. The stopped state is, for example, a state in which a holding operation for holding the original S discharged from the original discharge port 64 is continued. The position of the second travel path MD2 where the document S discharged from the document discharge port 64 covers the tip of the recording medium M is a position where the tip of the document S discharged from the document discharge port 64 is located below the intersection position CP including the intersection position CP. In other words, the position of the second advancing path MD2 where the document S discharged from the document discharge port 64 blocks the tip of the recording medium M is a position where the document S blocks the medium discharge port 58 when viewed from the-Y direction. Therefore, if the leading end of the recording medium M is discharged toward the medium discharge port 58 in the stopped state of the original S, there is a possibility that the conveyance jam may be caused.

Hereinafter, a specific control method will be described. In addition, since steps S101 to S106 in fig. 9 are the same as steps S11 to S16 in fig. 6, the explanation is omitted.

As shown in fig. 9, in step S107, the control unit 100 determines whether or not the leading end of the recording medium M is discharged from the medium discharge port 58. Specifically, the control unit 100 determines whether or not the leading end of the recorded recording medium M is in the vicinity of the medium discharge port 58. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data of the medium position detection unit 45. Further, since the position of the medium discharge port 58 is known, it is possible to easily determine whether the tip of the recording medium M is in the vicinity of the medium discharge port 58 by detecting the position of the tip of the recording medium M.

Then, as shown in fig. 10, when it is determined that the leading end of the recording medium M is in the vicinity of the medium discharge port 58 in the stopped state of the original S (yes), the control unit 100 proceeds to step S108. On the other hand, when it is determined that the leading end of the recording medium M is not in the vicinity of the medium discharge port 58 (no), the control unit 100 proceeds to step S106, and continues the recording operation.

In step S108, when the rear end of the original document S is nipped by the second driving roller 78, the control section 100 discharges the original document S by the second driving roller 78 as a discharge roller as a predetermined operation for releasing the stopped state. Specifically, the control unit 100 drives the conveyance motor 62M. As a result, as shown in fig. 11, the second driving roller 78 is driven to rotate, so that the original S nipped at the nip position N2 of the second driving roller pair 73 is released, and the entire original S is discharged from the original discharge port 64. Thereby, the stopped state is released, and the medium discharge port 58 is opened. Then, as shown in fig. 12, the recording operation is continued, and the recording medium M is discharged from the medium discharge port 58. The recording operation for ejecting the recording medium M includes an operation for conveying only the recording medium M.

As described above, according to the present embodiment, the stopped state of the original S is released before the top end of the recording medium M reaches the intersecting position CP. Specifically, the document S in the stopped state is discharged by driving the second driving roller 78, and the stopped state is released. In this way, since there is no case where the original S blocks the second advance path MD2 of the recording medium M, the discharge of the recording medium M can be smoothly performed without the recording medium M colliding with the original S.

In the present embodiment, the stopped state is released by driving the second driving roller 78, but the present invention is not limited to this, and for example, the distance between the second driving roller 78 and the second driven roller 79 in the second driving roller pair 73 may be set to be displaceable to a nip position N2 for nipping the original S and an open position for opening the nipped state of the original S, and the stopped state may be released by displacement to an open position for opening the nipped state of the original S.

2. Second embodiment

Next, a second embodiment will be described. In addition, the same components as those of the first embodiment will be denoted by the same reference numerals, and overlapping description will be omitted.

Fig. 13 illustrates a control method of the composite device 10 according to the present embodiment. In addition, since the contents of step S201 to step S207 are the same as step S101 to step S107 (fig. 9) of the first embodiment, the description thereof is omitted.

As shown in fig. 13, in step S207, when the control unit 100 determines that the leading end of the recording medium M is in the vicinity of the medium discharge port 58 in the stopped state of the original S (yes), the process proceeds to step S208. On the other hand, when the control unit 100 determines that the leading end of the recording medium M is not in the vicinity of the medium discharge port 58 (no), the flow proceeds to step S206, and the recording operation is continued.

In step S208, the control unit 100 conveys the original S in a direction opposite to the first discharge direction D1 until the position of the second travel path MD2 where the tip of the recording medium M is not blocked, as a predetermined operation for releasing the stopped state, before the tip of the recording medium M discharged from the medium discharge port 58 reaches the intersection position CP.

Specifically, as shown in fig. 14, the conveyance motor 62M is driven from a stopped state in which the discharge of the original S is stopped at a position of the second advance path MD2 that blocks the tip of the recording medium M. In the present embodiment, the conveyance motor 62M is driven to rotate in reverse. As a result, as shown in fig. 15, the upstream driving roller 74, the first driving roller 76, and the second driving roller 78 are reversely rotated, and the original S is conveyed in the direction opposite to the first discharge direction D1. The control section 100 stops driving of the conveying motor 62M, for example, when the rear end of the original S reaches a first detection position DP1, which is a detection position detected by the first sensor 651. Thereby, the stopped state is released, and the medium discharge port 58 is opened. Then, as shown in fig. 16, the recording operation is continued, and the recording medium M is discharged from the medium discharge port 58. Further, the control unit 100 may be configured to detect the position of the leading end of the original S by detecting the motor rotation amount of the conveying motor 62M, and convey the original S in the opposite direction to the first discharge direction D1 until the position of the leading end of the original S does not block the position of the second advancing path MD2 of the leading end of the recording medium M.

In step S209, the control unit 100 determines whether or not the leading end of the recording medium M is discharged from the medium discharge port 58. Specifically, the control unit 100 determines whether or not the leading end of the recorded recording medium M is discharged to the outside from the medium discharge port 58. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data of the medium position detection unit 45. In addition, since the position of the medium discharge port 58 is known, it is possible to easily determine whether the tip of the recording medium M is located outside the medium discharge port 58 by detecting the position of the tip of the recording medium M.

When the control unit 100 determines that the top end of the recorded recording medium M is discharged to the outside from the medium discharge port 58 (yes), the control unit 100 drives the conveyance motor 62M to rotate positively and discharges the original S in the first discharge direction D1 as shown in fig. 16 in step S210. In addition, in the case where the leading end of the recording medium M has passed the intersecting position CP, since the leading end of the recording medium M is discharged along the second advancing path MD2 even if the original S is discharged, the risk of conveyance jam is low.

As described above, according to the present embodiment, the original S is conveyed in the opposite direction to the first discharge direction D1 before the leading end of the recording medium M reaches the intersecting position CP, and thus, the second travel path MD2 of the recording medium M is not blocked. Therefore, the recording medium M can be smoothly discharged. Further, since the original S is not dropped from the original discharge port 64, damage to the original S can be suppressed.

In addition, with the present embodiment and the first embodiment, the user can select appropriately.

3. Third embodiment

Next, a third embodiment will be described. In addition, the same reference numerals will be given to the same structures as those of the first embodiment, and duplicate descriptions will be omitted.

In fig. 17, a control method of the composite device 10 according to the present embodiment will be described. In addition, since the contents of step S301 to step S308 are the same as those of step S101 to step S108 (fig. 9) of the first embodiment, the description thereof is omitted.

In the present embodiment, when the recording medium M is discharged from the medium discharge port 58 in a discharge state in which the original S is discharged, the control section 100 causes the recording medium M to be discharged toward the intersecting position CP even in a state in which the original S covers the second advancing path MD2 of the leading end of the recording medium M.

Hereinafter, description will be made specifically.

In step S304, the control unit 100 determines whether or not the count value counted by the counter exceeds a predetermined value, and when it is determined that the count value counted by the counter exceeds the predetermined value (yes), the flow proceeds to step S305. On the other hand, when it is determined that the count value counted by the counter does not exceed the predetermined value (no), the flow advances to step S309.

Here, the determination of the control section 100 in step S304 can be regarded as a determination as to whether or not the rear end of the original S passes the nip position N1. That is, the case where the count value counted by the counter does not exceed the predetermined value is a state where the rear end of the original S is located upstream of the nip position N1 of the conveying path FR and the original S is being conveyed downstream of the conveying path FR until it is determined that the count value counted by the counter exceeds the predetermined value, as shown in fig. 18. That is, the original S is in the discharged state. The discharge state may be either during reading of the original S or only during discharge.

In step S309, the control unit 100 determines whether or not the leading end of the recording medium M is discharged from the medium discharge port 58. Specifically, the control unit 100 determines whether or not the leading end of the recorded recording medium M is in the vicinity of the medium discharge port 58. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data of the medium position detection unit 45. Then, when determining that the leading end of the recording medium M is in the vicinity of the medium discharge port 58 in the stopped state of the original S (yes), the control unit 100 proceeds to step S310. On the other hand, when it is determined that the leading end of the recording medium M is not in the vicinity of the medium discharge port 58 (no), the control unit 100 proceeds to step S303.

In step S310, the control unit 100 continues the conveyance of the recording medium M. Specifically, the control unit 100 controls the recording mechanism 12 to perform a recording operation on the recording medium M and to convey the recording medium M.

That is, as shown in fig. 19, in step S310, the discharge of the original S and the discharge of the recording medium M are performed at the same time. In this case, the original S is discharged, and the medium discharge port 58 is blocked by the original S passing through the intersecting position CP, and in this state, the recording medium M comes into contact with the original S. However, since the recording medium M is in contact with the original S that is being discharged and moved downward along the first advancing path MD1, the discharge of the recording medium M is promoted by the pushing force accompanying the downward movement of the original S, and the recording medium M is discharged downward together with the original S.

As described above, according to the present embodiment, the recording medium M is discharged together with the discharge operation of the original S after colliding with the original S. Therefore, it is possible to reduce the conveyance jam of the recording medium M and simultaneously perform the discharge of the original S and the discharge of the recording medium M, so that the throughput of the recording process can be improved.

4. Fourth embodiment

Next, a fourth embodiment will be described. The same components as those of the first embodiment will be denoted by the same reference numerals, and repetitive description thereof will be omitted.

In fig. 20, a control method of the composite device 10 according to the present embodiment will be described. In addition, since the contents of step S401 to step S408 are the same as step S101 to step S108 (fig. 9) of the first embodiment, the description thereof is omitted.

In the present embodiment, when the leading end of the recording medium M passes through the intersecting position CP before the original S reaches the position where the medium discharge port 58 is jammed, the control section 100 causes the discharge of the original S and the discharge of the recording medium M to be simultaneously performed.

Hereinafter, description will be made specifically.

In step S404, the control unit 100 determines whether or not the count value counted by the counter exceeds a predetermined value, and when it is determined that the count value counted by the counter exceeds the predetermined value (yes), the flow proceeds to step S405. On the other hand, when it is determined that the count value counted by the counter does not exceed the predetermined value (no), the process proceeds to step S409.

Here, the determination of the control section 100 in step S404 can be regarded as a determination as to whether or not the rear end of the original S passes the nip position N1. That is, the case where the count value counted by the counter does not exceed the predetermined value is a state where the rear end of the original S is located upstream of the nip position N1 of the conveying path FR and the original S is being conveyed downstream of the conveying path FR until it is determined that the count value counted by the counter exceeds the predetermined value, as shown in fig. 21. That is, the original S is in a state before reaching the position where the medium discharge port 58 is jammed. Note that this state may be either during reading of the original S or only during discharge. Further, the original S may be stopped.

In step S409, the control unit 100 determines whether or not the leading end of the recording medium M is discharged from the medium discharge port 58. Specifically, the control unit 100 determines whether or not the leading end of the recorded recording medium M is discharged to the outside from the medium discharge port 58. Specifically, the control unit 100 detects the position of the tip of the recording medium M based on the detection data of the medium position detection unit 45. Then, when it is determined that the leading end of the recording medium M is discharged from the medium discharge port 58 (yes), the control unit 100 proceeds to step S410. On the other hand, when it is determined that the leading end of the recording medium M is not discharged from the medium discharge port 58 (no), the control unit 100 proceeds to step S403.

In step S410, the control unit 100 continues conveyance of the recording medium M. Specifically, the control unit 100 controls the recording mechanism 12 to perform a recording operation on the recording medium M and to convey the recording medium M.

That is, as shown in fig. 22, in step S410, the discharge of the original S and the discharge of the recording medium M are continued. In this case, the document S is discharged, and the document S passes through the intersecting position CP to block the medium discharge port 58, but the leading end of the recording medium M is already discharged from the medium discharge port 58. Therefore, since the tip of the recording medium M does not collide with the original S, the recording medium M is discharged downward together with the original S.

As described above, according to the present embodiment, since the tip of the recording medium M does not collide with the original S, it is possible to reduce the conveyance jam of the recording medium M and simultaneously perform the discharge of the original S and the discharge of the recording medium M, thereby enabling to improve the throughput of the recording process.

5. Other embodiments

When the original S is stopped at a position where the second advancing path MD2 is blocked by the tip of the recording medium M, the control unit 100 may notify the operator 15 of the removal of the original S from the reading mechanism 11 as a predetermined operation for releasing the stopped state. As a notification method, for example, a warning display may be displayed on a display panel of the operation unit 15, or a warning sound may be generated from the operation unit 15. In this way, the original S in the stopped state can be removed by the notification by the operation unit 15 before the leading end of the recording medium M reaches the intersecting position CP, and the recording medium M can be smoothly discharged without blocking the second travel path MD2 of the recording medium M.

For example, when the document S is jammed and stopped on the conveyance path FR, the control unit 100 may notify the user of the jam of the document by the operation unit 15 while maintaining a state in which the document S is stopped from being discharged from the document discharge port 64. In this way, damage to the original S can be prevented.

For example, when the original S is stopped in the middle of reading the original S on the conveyance path FR due to a conveyance failure or the like, the control unit 100 may restart reading the original S before the leading end of the recording medium M discharged from the medium discharge port 58 reaches the intersecting position CP. In this way, if reading is restarted without stopping the original S, even if the recording medium M collides with the original S, the risk of conveyance jam can be reduced. In this case, the control unit 100 conveys the original S in the opposite direction to the first discharge direction D1 by a predetermined amount before restarting the reading of the stopped original S, and then restarts the reading of the original S.
